Fastest SOB hull???

[dnelson964]

You forgot about this Superboat 21 was running very fast on the Ct run

Yes, nice boat and one of the few 21's that made it over and back from 2012 Ct. River Run. He even still ran over after losing his cowling in first few minutes of rough seas. I give Rick

Rick would attach the seat to the engine and drive like that if he had to

Greg- Progression is all balsa, even the stringers and transom. He also weighs every hull and deck.

Thanks RobF, a little info on coring and balsa ...............

In an effort to build a stronger, lighter hull, builders began constructing hulls with a cored material sandwiched between layers of fiberglass. While more labor intensive, the end product is alighter and stiffer hull. There are anumber of material used for coring, including end grain balsa, Airex and Divinycell. In addition, plywood may be used in transoms, as well as in decks on boats of any length. End grain balsa has the advantage of being very light and stiff, but can absorb water if not completely sealed. Airex is a synthetic, also light, but more flexible. Divinycell, also a synthetic, is stiffer than Airex. Both synthetics are less prone to absorbing water. Plywood,while not as light, is stiff and gives light fiberglass sections an increased load carrying capacity, but it is also susceptible to absorption.Cored materials have been used successfully for a number of years. Generally, coring is not found in boats until the mid-30 ft.range. There may be a few exotic species for racing that do, but the vast majority of the smaller boats on Lake Superior and elsewhere simply aren'tcored. A method of checking for a cored material is by tapping the hull with a small plastic hammer. As the hammer (lightly) strikes the fiberglass hull, a clear, crisp report should be heard. If the report is dull and sounds like a watermelon, there may cored material that is wet. A hammer will not definitively tell you there is core material, but it will aid in finding wet and/or delaminated core.

Hey guys, this has been an awesome thread really been enjoying reading through all this, deff a lot of info here. My Velocity has a stock Merc 300x ran 93 with a 27 Hydromotive, not sure exactly on rpm because I'm always so focused on gps I forget to look lol and then always beat my self up about it later. Got this speed on a lake also so no BS tide #'s from me. Haven't had a chance to do to much prop testing, really just been running it with the hydromotive, once I get my hands on a pro et I expect to see quite a bit more out of it. Can't wait to see what it will do.

Hopefully this thread will lead to the rebirth of Wednesday nights for the long island boys!

300 Yamaha 32 bravo on the limiter

Seeing as a good friend of mine is now the Sutphen dealer, I will get a fair bit of seat time in them.... And one 21 is the 525 boat that did 93mph. Will be interesting to see what it really will do and how they compare.

I got some additional feedback that the Merc 525 I/O Sutphen 21 that you mentioned your friend now has in stock was actually built with an extra layer of glass and an extra bulkhead. I don't know what that translates into in terms of added weight (another 150lbs?) over a standard layup, but it makes a top speed of 93 that much more impressive.

[Superbender]

Hoser no disrespect intended,but you where on the top five list and I didn't know your rpms or prop sorry,Brabender doesn't own a sob so he is out,and what can any one say about ghost, 23 kyrptonite 300pm 6400rpms 27 tempest77mph.there are others I just didn't have enough info on pm me and I'll add you to the list.Thanks there are some out there that still need to come clean about whats under there hood just sayin.

Superbender, are you talking about the Kryptonite 23 pictured below? Is this a 2005 and the only 23 Kryptonite built?
